The fighting between Israel and Palestinians in the Gaza strip over the last few days is the latest round of violence in a region that has been torn apart by a decades-old conflict. But the debut of Israel’s Iron Dome missile defense shield has added a new element to the conflict, one that military officials are calling a “game-changer.” Why is Iron Dome such a significant addition to Israel’s military arsenal?
Iron Dome actually works. Israeli officials are claiming that the shield is destroying 90 percent of missiles and rockets it aims at that have been fired into southern Israel by Hamas. This level of success is unprecedented compared with older missile defense systems such as the American-made Patriot model used during the 1991 Gulf War. Israelis have almost always suffered far fewer casualties than Palestinians have, but Iron Dome has made that disparity even larger. As of Monday, Israel has reported three casualties, all of which occurred during a temporary malfunction in the missile-defense system.
The missile-defense system can detect rocket launches and then determine the projectiles’ flight paths. Iron Dome intercepts rocket or artillery shells only if they are headed for populated areas or sensitive targets; the others it allows to land. After pinpointing a rocket for destruction, Iron Dome fires a warhead that destroys the rocket within seconds. Currently, five Iron Dome systems are deployed in Israel. Most are located in the south, near Gaza, and each operates with a 45-mile radius.
Israeli officials point out that Iron Dome saves money despite the fact that the interceptors cost up to $100,000 each. The cost of rebuilding a neighborhood destroyed by a rocket attack—not to mention people wounded and lives lost—would be far greater than the cost of the interceptor. In addition, the system buys Israel time, allowing it to plan out an appropriate response without the political pressure that would be generated by hundreds of potential deaths. Experts have called Iron Dome’s success a crucial factor in deterring Israel from launching a ground assault on Gaza.
